Abstract
Two methods of hydrogen bulk passivation in multicrystalline ingot silicon solar cells were compared. After POCl3-emitter diffusion, four different solar cell types were made out of neighbouring wafers. The first wafer was not hydrogen passivated. The second wafer was passivated by firing of hydrogenated silicon nitride (SiN:H). On the third wafer, a microwave induced remote hydrogen plasma (MIRHP) was applied. The fourth wafer was passivated by both techniques. On all wafers, the recombination activity of dislocations was measured by the correlation of light beam induced current (LBIC) with dislocation density topography. Recombination at grain boundaries was examined using LBIC line scans. The spatial resolution of the measurements was 12.5 μm.
